The picture above shows a 3 by 3 board with two missing corners.
There are 3 blue chips on the yellow part of the board and 3 yellow chips on the blue part of the board.
The rules are as follows:
- You can move a chip from one square to a square next to it if the square is empty.
- You can jump a chip over a different coloured chip next to it as long as you land in an empty space.
- You cannot move or jump diagonally.
The problem is to put the blue chips on the blue part and the yellow chips on the yellow part, i.e. switch the chips' positions.
